This invention relates to loaders capable of handling various kinds of materials to gather said materials and place them onto a conveyance or to place said materials at a selected locality within a pile and has for the primary object the provision of a device of this character which may be readily installed on a conventional type of tractor and receive power therefrom for its operation, being under direct manual control of 0 the driver of said traetor.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and w claimed. p l

For a complete understanding of my invention, reference is to be had to thefollowing description and accompanying drawings, in which Figure 1 is a fragmentary top plan view illustrating a loader adapted to a conventional type of tractor and constructed in accordance with the present invention. Y

Referring in detail to the drawings, the numeral 5 indicates a conventional type of tractor o on which the present invention is mounted. Ar-

ranged at thev front end of the tractor is a vertically disposed hoist frame 6 bolted or otherwise secured on the forward end of the frame andar- -ranged so as to straddle the front wheels of the tractor. The frame 6 is further secured to the tractor by braces 'I. The vframe 6 includes ver-A 'tically arranged side members 8 anda plurality of horizontally 'arranged cross members 9 and is further provided with vertically arranged members II) arranged inwardly of the vertical members 8 and secured to the horizontally arranged members 9. The various members are suitably joined'with each other and -reinforced by braces II.

56 Scoop carrying levers I2 are pivoted on the of the bottom wall of the scoopsothat saidreinrear axle housing of the tractor, as shown at I3, and extend forwardly and terminate at a selected distance beyond the forward end of the tractor as well as the hoist frame 6. The levers I2 are arranged on opposite sides of the tractor 5 and have pivotally mounted thereon a scoop Il which may be readilyconverted into aloading fork by. removing a section I5 of the bottom of the scoop. The scoop includes side walls I6, a rear wall I'I and a bottom wall I8. Reinforcing m members I 9 vare secured on the bottom wall of the scoop and extend beyond the forward edge thereof to form penetrating points and are detachably connected to the removable section I5 forcing members then will act as the tines of the fork@ The scoop is pivoted of-center so that -it will naturally move into an inclined position as shown in Figure 4. To support the scoop horizontally or in a plane substantially with the 20 plane-of the levers I2, a spring influenced c atch I8 is provided on a cross member I9' connecting the levers I2 forwardly of the front end of the tractor. The catch I8'v coacts with a keeper 2D carried by a frame structure 2| on the rear 25 wall of the scoop to releasably secure the scoop in a plane substantially with the plane of `the levers. To release the catch I8' from the keeper an arm 22 is pivotally mounted on one of the levers I9 and engages the catch and is connected 30 to a link 23. The link 23 is pivotally connected lto a control pedal pivotally mountedon'one of the levers I2 and is located' adjacent to the operators seat on the tractor so that the operator. may at any time desired release the-catch 35 from the keeper 20 and free the scoop to assume a dumping position, as shown in Figure 4, by placing pressure on the pedal 24 with a foot. Journaled on the upper-portion of the frame 6 and arranged horizontally is a drum shaft 25 40 and secured on said shaft are drums 26 having A grooves 28 to receive hoisting cables 29. The cables 29 wind in the grooves of the drums by the, rotation of the shaft 25. The cables are connected to coupling elements 30 which join said cables with the elevating levers.l2. Each drum is provided at one end with .a flange 3l to pre vent-the cable of said drum from creeping olf of fthe drum during the rotation of the shaft.

A brakeshaft 32 parallels the drum shaft 25 J0 and is journaled on the frame Ii in a plane below the drum shaft and is connected to saidk drum shaft by gears 33. A brake drum 3l is secured on the brake shaft 32 and is engaged by a brake band 35, one end of which is secured on one of lrod BI.

vmembers I9 of the frame 6 in a plane below the brake shaft 32 and is connected' thereto by an endless sprocket chain 42 trained over sprocket gears 43 secured on the shafts 4I and 32.

Journaled on the vertical members l0 of the frame 6 in a plane below the driven shaft 4I is a power shaft 44 equipped with a pulley 45 ern--` ployed for belting the power shaft to a power takeoff of the tractor.

A clutch 46 is associated with the power shaft and includes a gear .41 meshing with a gear 48 secured on the driven shaft 4I. The clutch 4S is of the multiple disc type, as shown in Figure '1, and includes a housing consistingvof sections 48 and 49. The section 49 has the gear 41 formed thereon while the section 48 receives the section 49 therein and is' keyed on the power shaft 44 while the section 49 is rotatably supported by the power shaft. Certain of the discs or plates of the clutch are keyed to the section 48 whilefother lof the plates are keyed to the section 49' and when said sections are movedtoward each other brings about binding of the plates thereby establishing a drive from the power shaft tothe driven shaft.

A boxing Slis secured on the drive shaft 44 and has pivotally mounted thereon a clutch operating aun 5I`which engages the section 48 of the clutch and includes an extension 52 having a set screw 53 adaptedto ride a cone-shaped cam 54 splined on the drive shaft and is provided with a' groove 55 to receive a'fork 59 forming a part of a clutch operating lever 51 plvotally mounted on a bracket 58 carried by the frame I9. The clutch lever when moved in one direction will engage the clutch and when moved in Van opposite direction will permit the clutch to become disengaged, it being understood that the clutch plates carried -by the sections 48 and 49 move apart at this time so that the drive'between the drive shaft'44 and the driven shaft 4I will beinterrupted. A curved Alever 59 is connected to the clutch lever'51 by a link 60 and the curved lever 59 is connected to the control lever 39 by a connecting rod 40. v'I'hus it will be seen that when the clutch is operated the4 brake alsowill be operated.` In other words, when the clutch is disengaged to interrupt the drive be-A velevation with respect to the ground when power is interrupted to the driven shaft.

It is to be lunderstood that the clutch becomes disengaged, just prior to the applicationof the brake'so that if it is desired to lower the scoop it can be prior tothe application of the brake depending von the position occupied by the control lever 39. ,1 .'k Y

"A'flexible Yelement 62 is connected to the frame 2 I of the scoop and passes over a pulley 69 on theV frame I9 andis connected to a coil spring 64. The

coil spring 64 is in turn connected to one of the member-sill o f the frame 6. The purpose of. thel flexible. element is to move the scoop out of dumping position after a predetermined downward movement of the levers I2 so'that the scoop will be in operative position and the catch I8 in engagement with the keeper 20 when the scoop comes in' contact with the ground.

From the foregoing description, taken in connection with the drawings, it will be seen that the operator of the tractor from a seated position will have full control over the operation ofthe scoop. At the will of the operator the scoop may b e lowered into engagement with the ground for the purpose of gathering or taking up material. The operator then through the manipulation of the lever 39 may bring' about elevation of the scoop to a desired distance from the ground whence the tractor may carry the material in the scoop to any place desired or for dumping onto a conveyance. To dump the scoop the operator presses the pedal 24 which disengages the catch I8' from the keeper and the scoop automatically assumes dumping position due to the fact` that it is pivoted olfcenter. As soon as the scoop is moved a predetermined distance toward the ground the ilexible element 62 acts on the scoop to position the latter in operative position with the'keeper in engagement'with the catch I8.

then act as tines whereby hay, straw and other material may be readily gathered and conveyed to a selected place by the device.

It is believed that the foregoing description, I .when taken in connection with the accompanying f' drawings, will fully setforth the construction and advantages of this invention to those skilled'in the art to which such invention relates, vso' that further-detailed description will not be required. l.

AWhat I claim is:l

A loader for use on a tractor having a rear axle housing and a chassis comprising a pair of scoop elevating bars pivoted at rear ends thereof on said axle housing for vertical swinging .movev to bersecured to the front end of the chassis in upstanding position and extending transversely of the chassis intermediate said bars, a transversely extending hoisting drum shaft on said frame adjacent the top thereof, a pair of drums on'opposite ends of said shaft, cables operatively connecting said drums to -said bars, respectively, a transversely extending brake shaft on said frame below said drum shaft and geared to said drum shaft,

a driven shaft on said frame below said brake shaft, a. sprocket and chain drive"be'tween said driven and brake shafts, a power shaft on said `frame below said driven shaft for connection to a source of power, a 'clutch on said power shaft having a driven member geared to said driven shaft and a. shiftable driving member, a brake drum on the brake shaft, a brake band for applying friction to the brake drum, and a control lever -adjacent the rear end of said bars, operatively v connected to said band and to the shiftable driv- .ing member to alternately shift said member and engage s aid band with said brake drum, said shafts being arranged in a common vertical plane on said framevto economize in lateral space.
